[Abstract]:Permanent magnet rotor multi-degree-of-freedom motor can realize the motion of output shaft, simplify the structure of motor mechanical system, and improve the response speed and positioning accuracy of transmission system. It is a research hotspot in the field of motor at home and abroad. In this paper, a butterfly permanent magnet rotor deflection motor with three degrees of freedom is proposed. The 3D finite element model of the motor is established based on the finite element method, and the magnetic field distribution of the rotor is calculated and analyzed. The results are compared with the analytical model. On this basis, the rotation torque and deflection torque of the motor are calculated and analyzed, and compared with the magnetic field and torque of the drum permanent magnet rotor deflection motor with three degrees of freedom. The results show that the butterfly permanent magnet rotor deflection motor can increase the flux density of air gap and the amplitude of rotation torque, improve and increase the amplitude of deflection torque, and increase the range of deflection motion. Finally, the prototype is tested, and the experimental results are compared with the calculated results of finite element and analytical models.
